Employee Owned...Customer DrivenAs of 2008, Rex-Cut became 100% owned by its employees. Those loyal employees who have poured themselves into Rex-Cut over the years, now have reason to be even more invested in the product and service that leaves our premises, as well as our future success.

We believe that working together with our new “employee-owners” will help us remain competitive and focused in future years. Our products, our high level customer and technical service, and our previous management structure all remain intact. We are confident we will get even better at what we do, so it’s a win/win/win for all—previous owners, all new employee owners, and our fine customers and business partners.

We are more excited than ever about what the future holds for our company. To all our previous and current customers we say “Thank you” for your business--for allowing us to service your specialty abrasive needs. For all new customers we say “welcome aboard”, and we hope you will allow us to prove to you why Rex-Cut is the place to turn to cost-effectively satisfy your deburring and metal finishing needs. We value the confidence and trust of our customers worldwide. The Executive Management Team.

Rex-Cut Products, Inc. is the oldest and primary manufacturer of cotton fiber abrasive grinding and finishing products in the world. Since the late 1920s, we have been manufacturing a non-woven cotton fabric, uniquely impregnated with abrasive grit. This “impregnating” process, originally invented by our founder Edward Hurst, has been refined over time and continues to be the foundation of our specialized cotton fiber abrasive product line.

Rex-Cut has a proven record of being able to explore, develop and con sis tent ly manufacture products that meet and exceed customer ex pec ta tions. Our product quality, performance and safety is exceptional.

In addition to our cotton fiber abrasive product line, we continue to expand our offering with only the highest quality resinoid, coated, and non-woven products.

Refer to American National Standards Institute, ANSI B7.1-2000, Safety Requirements for the Use, Care and Protection of Abrasive Wheels or contact us directly with any questions you might have regarding usage of any of our abrasive products.

Rex-Cut cotton fiber abrasives are man u fac tured using a unique im preg na tion process that pro vides superior bonding and con sis ten cy in its product line. Each step in manufacturing an in di vid u al product is closely con trolled, from the staple length of the raw cotton to the final mark ing of the RPM on a finished abrasive wheel.

For over 80 years our unique non-woven cotton fiber abrasive products have been successfully servicing the international market. In terms of performance, consistency, and quality, our specialized abrasive impregnating process has repeatedly demonstrated to our customers a technology that is unmatched in the world today.

Rex-Cut cotton fiber products are bonded laminates of non-woven, abra-sive impregnated cotton fabric. Varying hardness of bond is available to produce products suitable for application on stainless steel, alu mi num, and exotics.

Cotton reinforced abra sive prod ucts are used through out the world for a va ri ety of ap pli ca tions re quir ing medium to light duty metal removal, deburring, and finishing.

sPECiAl FEA TurEs AnD ADVAnTAgEs• Fast, One Step Finishing:The composition of Rex-Cut’s abrasive products enables grinding and finishing in one operation. They have consistently reduced finishing steps from two or three to one.

• Versatility:The wide range of applications on which cotton re in forced products are used, make them one of the most versatile of all abrasive tools. From the ag gres sive stock removal of TX (resin) bonded products to the finishing per for mance of FX (latex) bonded products.

• Cool Cutting Action:Our unique con struc tion continually exposes new abrasive grain during the grinding process resulting in cooler op er a tion, and no back transfer or smear ing.

• Smooth, Quiet Action:With its soft cushion-like grinding action, the com po si tion of cotton reinforced products makes them resilient, smooth handling and quiet. Any tendency toward vibration and chatter is reduced.

• Non-Loading:Unlike most bonded or coated abrasives, cotton reinforced wheels do not load up when working on softer metals or alloys, such as aluminum. The use of Rex-Cut products eliminates the need for messy wax gen er al ly used to prevent bonded or coated products from loading.

• Long Life:Our products not only offer long life on the original job, but they can be dressed down and utilized on other applications.

APPliCATiOnsIndustries using cotton reinforced abrasive products include aircraft, aerospace, ship building, jewelry, tool and die, automotive, food pro cess ing, dairy, cutlery, welding trade, general fab ri ca tion, and others. Rex-Cut’s complete line of cotton reinforced Type 1 straight sided abrasive wheels, Type 27 de pressed center wheels, Mounted Wheels and Points, Quick Change Discs, and Sticks meet a wide range of grinding, blending, and finishing needs.

NEW & IMPROVED


Designed for those demanding applications requiring fast, heavy, and controlled stock removal. Rex-Cut offers a complete line of burs while stocking popular sizes.

standard Cut• generalpurpose

Double Cut•finerfinish,smallerchips•smootheroperatorcontrol, less vibration

non-Ferrous Cut•widerflutesforreduced loading•excellentforaluminum, plastic, and non-ferrous metals

All burs are manufactured using grade K20 micrograin carbide and high speed, heat treated, steel shanks. All brazed burs are 100% torque tested for the safest operation.

General Information for Bur Use1. It may be necessary to adjust the bur

speed as shown on above for optimum performance.

2. Use slower speeds for harder materials.3. Use faster speeds when using small

burs.4. Apply constant pressure and movement

when in use.5. Running burs below recommended

speeds may cause chipping.6. Do not use worn out tools and collets as

they will also cause chipping. 7. Running burs too fast will cause teeth to

wear prematurely.

The following safety information should be used only as a guide for the Rex-Cut range of products.1. Check all wheels for cracks or other damage before mounting.

2. Check machine speeds against maximum operating speed of the wheel.

3. Be sure that the wheel bore, threaded or unthreaded, fits machine arbor properly and that flanges are clean, flat and of the proper type for the wheel you are mounting.

4. Run the wheel in a protected area at least one minute before grinding.

5. Wheels must be properly guarded.

6. Wear protective safety glasses or a proper face shield.

7. Do not use wheels which have been dropped or otherwise damaged.

8. Do not use excessive pressure when mounting wheels between flang es. Tighten nut sufficiently to hold wheel firmly.

9. Do not use heavy side grinding pressure on any Type 1 straight sided wheel.

10. Do not mount more than one wheel on a single arbor.

storageRex-Cut Wheels should be stacked flat, not on their edges, in a dry area.

RPM / SFPM Speed Conversions

Definitions:SFPM = Surface Speed in Feet per MinuteRPM = Revolutions per MinuteM/S = Meters per second

The SFPM for most T27 bonded grinding wheels is approximately 15,600. Note that this is equal to the European standard of 80 M/S or 13,300 RPM for a 4-1/2” diameter wheel.

Calculations:- to convert RPM to SFPM ............ SFPM = (RPM x DIA) / 3.82- to convert SFPM to RPM ............ RPM = (SFPM x 3.82) / DIA- to convert M/S to SFPM ............. M/S x 197- to convert SFPM to M/S ............. SFPM x .005

For more information regarding Safe Operating Speeds, refer to ANSI B.7.1 Table 23 - “Standard maximum speeds in surface feet per minute” and Table 35 - “Conversion Table - Wheel speeds”.
